Claims priority, application Sweden October 29, 1954 4 Claims. (Cl. 131-52) The present invention relates to machines having a rolling table and a rolling apron for winding tobacco, or tobacco articles, into tobacco leaves, for example in the manufacture of tobacco products having configurations like cigarettes.

In known such machines, which are similar to cigar bunch making machines, the tobacco leaf is ordinarily pasted to produce a seam, and paste is likely to adhere to the rolling apron so that the wound article might stick thereto and be retracted by the rolling apron when moving back into its initial position, or said article will adhere only slightly to said apron so that it will drop from same in an irregular manner and be positioned incorrectly relative to means provided for cutting its ends.

It is an object of the present invention to remove this drawback. Accordingly, the invention contemplates the provision, below said edge of the table, of a suction nozzle connected to suction means and constituting a receiver for the wound product.

An embodiment of the machine according to the invention is hereinafter described, by way of example, with reference to the accompanying drawings, in which:

Figure 1 is a vertical sectional view of the front portion of the machine.

Figure 2 is a front elevational view of said machine, and

Figure 3 is a vertical sectional view of certain features of the machine in other operative positions than in Figure 1.

Referring to the drawings, the machine has a rolling apron 2 placed on a perforated rolling table 1 and operated by a bunch roller 3 which, inthe same manner as in an ordinary cigar bunch machine, operates the apron 2 to move forwardly and rearwardly over the rolling table 1 to form a tobacco article 4 by winding filler tobacco or a cigarette into a tobacco leaf placed on the apron whereafter the roller 3 is retracted and the apron 2 is moved back by means (not shown). The roller 3 is mounted on a forked lever 5 which is secured to a shaft 7 rotatably journalled in the machine frame 6. The lever 5 is reciprocated by means of a cam disc 13 secured to a rotatable shaft 14.

At the front edge of the rolling table 1, the wound article 4 is delivered by the apron 2 to a receiver 15, which consists of a suction nozzle connected to a suction conduit 16 which in turn is connected to any suitable suction source, conveniently the one to which an interior chamber of the perforated rolling table 1 is connected. Figure 1 shows the position of the tobacco article 4 just 2,854,009 Patented Sept. 30, 1958 ice before the rolling apron 2 is about to project beyond the front edge of the rolling table 1 and be tensioned.

In Figure 3 the article 4 rests on the receiver 15 when the suction effect in the latter has ceased and the rolling apron 3 has been retracted somewhat and tensioned.

From the suction nozzle 15 the tobacco article 4 is elevated by a carrier 17 consisting of a pair of legs and driven in well known manner by the cam disc 13 actuating the lever 5. Said carrier 17 moves the article 4 against two stationary scissor legs 18 so that its ends will be cut oif, whereafter the article is moved further and delivered by the carrier 17 to the second receiver 19 from which it can be transmitted for further treatment.

I claim:

1. A machine for winding filler tobacco or rod-shaped tobacco articles into tobacco leaves to form a wound product, comprising a rolling table and a rolling apron arranged for delivering the wound product at an edge of said rolling table, a stationary suction nozzle located in front of and extending lengthwise of said edge of the table and having an upwardly directed suction opening which is narrower than said product and has side walls adapted to support the wound product, said suction nozzle being connected to a suction source.

2. A machine for winding filler tobacco or rod-shaped tobacco articles into tobacco leaves to form a wound product, comprising a rolling table and a rolling apron arranged for delivering the wound product at an edge of said rolling table, a stationary suction nozzle located in front of and extending lengthwise of said edge of the table and having an upwardly directed suction opening which is narrower than said product and has side walls adapted to support the wound product and end walls having curved concave upper edges adapted to the cross sectional shape of said product, said suction nozzle being connected to a suction source.

3. A machine for winding filler tobacco or rod-shaped tobacco articles into tobacco leaves to form a wound product, comprising a rolling table and a rolling apron arranged for delivering the wound product at an edge of said rolling table, stationary suction means extending lengthwise of, below, and in front of said edge of the table and having an upwardly directed suction opening having edges for supporting said product.

4. A machine for winding filler tobacco or rod-shaped tobacco articles into tobacco leaves to form a wound product, comprising a rolling table and a rolling apron arranged for delivering the wound product at an edge of said rolling table, a stationary support for said product located in front of and below said edge of the table and having a suction nozzle for retaining said product on said support, and suction means connected to said nozzle.
